Abstract
Oxidative coupling of the 1,4-dicarbanions derived from bis-1,4-(diphenylphosphinyl)butane gave (±)-trans-bis-1,2-(diphenylphosphinyl)cyclobutane. Asymmetric hydrogenation of dehydroamino acids using rhodium complex of the optically active bisphosphine obtained by reduction of the resolved bisphosphine oxide afforded hydrogenated products in high optical yields.
